Ok. I am definitely making use of the zombie detection (pre-greeting, etc.), but I also use the DNSRBL’s on postscreen. I was under the possibly mistaken impression that this was a bit more efficient instead of having a spam source connect, possibly negotiate STARTTLS and then start a SMTP transaction and then have it rejected based on smtpd restrictions. Should I then continue to use postscreen for the zombie detection but then move my DNSRBL entries to smtpd restrictions ? Apologies for belabouring the point - I’m just not understanding. Thanks, - J
